Entanglement Asymmetry and Quantum Mpemba Effect for Non-Abelian Global Symmetry
Harunobu Fujimura, Soichiro Shimamori
Entanglement asymmetry is a measure that quantifies the degree of symmetry breaking at the level of a subsystem. In this work, we investigate the entanglement asymmetry in $\wideha…
The SymTFT for -ality defects: Part I
Justin Kaidi, Xiaoyi Shi, Soichiro Shimamori +1
In order to obtain the SymTFT for a theory with an -ality extension of a discrete, Abelian group , one begins by considering a bulk -gauge theory, and then gauges an appro…
Localized RG flows on composite defects and -theorem
Dongsheng Ge, Tatsuma Nishioka, Soichiro Shimamori
We consider a composite defect system where a lower-dimensional defect (sub-defect) is embedded to a higher-dimensional one, and examine renormalization group (RG) flows localized…
Subdimensional Disorder and Logarithmic Defect
Soichiro Shimamori, Yifan Wang
We study quenched disorder localized on a -dimensional subspacetime in a -dimensional conformal field theory. Motivated by the logarithmic behavior often associated with diso…
Boundary Scattering and Non-invertible Symmetries in 1+1 Dimensions
Soichiro Shimamori, Satoshi Yamaguchi
Recent studies by Copetti, Córdova and Komatsu have revealed that when non-invertible symmetries are spontaneously broken, the conventional crossing relation of the S-matrix is mo…
New Field Theories with Foliation Structure and Subdimensional Particles from Godbillon-Vey Invariant
Hiromi Ebisu, Masazumi Honda, Taiichi Nakanishi +1
Recently, subdimensional particles including fractons have attracted much attention from various areas. Notable features of such matter phases are mobility constraints and subexten…
